should download the version (delorean-light-theme-3.6) from the top of this page. Unzip the archive, and copy the delorean-light-theme-3.6 folder to /usr/share/themes/ *This theme can not be installed in ~/.themes. It will not work properly when installed within this directory!

Fixes:

Ubuntu Software Center: Make certain that you have the delorean-light-theme-3.6 installed in '/usr/share/themes/' before you continue.1. First backup the original files. In terminal with root(administrator) privileges type the following:

LinuxMint & Ubuntu with Unity: Slow Window Animations. Should you experience problems with window opening and closing animation the fix is to remove the 'metacity-theme-3.xml' file from the included 'metacity-1' folder.

It's hard to explain the menu, actually the problem is that the background of the menu is black and the fonts too hence the problem.

I can send you a picture with the type of menus I refer to. For instance, if you open VLC and go to tools->preferences you get a new Window. In there is an option menu called "Force Window Style". If you click there any option is invisible. You have to put the mouse over each of them to make them visible.

The background image causes this theme to be heavy. Its the trade-off for having the metallic background image. As for benchmarking, I seem to recall an app that did that for gtk2 years and years ago. I have know idea what it is, or if it still even exists. Metacity, however come with a built in benchmark app.
